Well, I'm not - I'm probably only just starting to feel a little nervous. It would be nice to see a couple of players come in but I'd even not be too concerned if we picked up a few for squad depth that aren't "superstars". Any more than 2 incoming players would concern me as, especially if they were to be 1st teamers, we'd have another bedding in period. At some point we need to stabilise and only bring through players who are going to replace players leaving or retiring.
We finished top last season whilst bedding in Aguero, Clichy, Nasri (3 first teamers) and a backup CB in Savic. Also we lost Tevez on a golfing holiday for 6 months and the Toure's to ACON. Finally we had some daft red cards for VK and Mario. Tevez is back (still think Id' be happier if we got rid) and the team have now had a season together with a PL title in the bag.
I honestly believe this team has another gear it can step up to which we saw in spots last season, first half at the Bridge springs to my mind where we looked like the home side and were battering them. If we can start to perform like that on a consistent basis then my only concerns over next season would be if we had some injuries to key players.
Going by the threads I've read I've also noticed a distinct lack of panic in people's posts.
